Protocols

This example shows the usage of two behaviours provided by JADE that implement the 'fipa-query' protocol and the 'fipa-request' protocol.

 - Initiator.class
This agent plays initiator role in a conversation following standard 'fipa-request' or 'fipa-query' protocol. It sends a REQUEST, a QUERY-IF or a QUERY-REF to a set of agent passed as argument.
 
 - Responder.class
The companion agent of Initiator.This agent plays responder role in 'fipa-request' and  'fipa-query' protocol  according to the messsage received.
 If a REQUEST arrives it answers random in one of the following way:
   - send an AGREE message and then an INFORM message
   - send an AGREE message and then a FAILURE message
   - send an AGREE message and then no message (in this case the Initiator agent will wait forever for the INFORM/FAILURE message)
   - send an AGREE message and then an out of sequence message
   - send an INFORM message
   - send a REFUSE message
   - send a NOT_UNDERSTOD message
   - send an out of sequence message
   - send no message

 If a QUERY-IF/QUERY-REF message arrives if replies in one of the following way:
   - sends a NOT_UNDERSTOOD message
   - sends a REFUSE message
   - sends a FAILURE message
   - sends an INFORM message
   - sends an out of sequence message
   - sends no message

 - ProtocolTest.class
This example using the inProcess interface permits the user to launch a JADE main container  with one Initiator agent and set of Responders,
For examples  the following command line:
java examples.protocol.ProtocolTester receiver1 receiver2 receiver3
start an Initiator agent sending message to the three Responders: receiver1, receiver2 and receiver3.

- ComplexInitiator.class
This example shows how to use the AchieveREInitiator protocol and register another initiator behaviour to handle one of the states of the protocol.
